Firefly and PC GAMESS-related discussion club

In a fullerene like structure the optimization process started successfully and passed several steps tillreached the current input file as you can see as attachment. When I tried to restart the job, Firefly requested more memory than former may be since the central atom is now closer to the fullerene and it is a new system. But this memory requirement is too much than I had expected so I was trying to turn off the direct scf and so on and all my efforts were not successful. I am thinking to use hard disk instead of memory but couldn't find any instruction in the manual. Would you please let me know whether there is a way to reduce the memory requirement of my job.
